Product Description:

The MSK076C-0300-NN-S1-UP0-NNNW is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a torque source for industrial automation, it is used to drive packaging stations, gantry axes, and other closed-loop motion modules that need accurate positioning and repeatable speed profiles. In a typical axis system, it converts regulated current from the servo drive into controlled rotary motion for indexing, feed, and transfer tasks. This operating role suits machinery that depends on repeatable starts, stops, and speed changes during each cycle. The encoder is a single-turn type, so the absolute position resets after one mechanical revolution and suits many point-to-point or cyclic processes. Size 076 and length code C indicate the stator and stack dimensions associated with the motor's torque density.

This motor is cooled by natural convection, so the housing should be mounted where free airflow can carry away heat. An IP65 enclosure keeps dust and low-pressure water jets away from the stator and bearings. Feedback is transmitted over the Hiperface digital interface through a rotatable 240° connector, which helps with cable routing in tight spaces and reduces sharp cable bends at the entry point. Inside the encoder, an optical scale with 128 signal periods works with optical sensing elements to provide high-resolution single-turn position data. This feedback path gives the drive the rotor position data needed for commutation and position correction during motion. Insulation class 155 supports the winding temperatures reached during cyclic acceleration.

This design is supplied without a holding brake, so static load retention must be provided by external mechanics or drive torque. Continuous operation is specified for ambient temperatures of 0–40 °C, allowing installation next to standard control electronics without forced cooling. The electromagnetic layout uses winding code 0300, which matches the coil resistance and inductance expected by compatible IndraDrive inverters. Mechanical power is delivered through a shaft with keyway, giving a positive connection to couplings or pulleys while preserving axial alignment. A keyed shaft can transfer torque directly to hubs, pulleys, or geared couplings without relying only on clamping friction.
